[0 aZZ whom it may concern:

Be it known that 1, WILLIAM J. KENNY, of Mortonpark, in the county'ofCook and State of Illinois,,have invented certain new and usefulImprovements in Machines forFlanging Can-Bodies; and I do hereby declarethat the following is a full, clear, and exact description thereof,reference being had to the accompanying drawings, and to the letters ofreference marked thereon, which form a part of this specification.

This invention relates to a novel machine employed in manufacturingsheet-metal cans.

The invention refers, primarily, to a novel construction for forming onthebody-wall or can-body of cans flanges by which the top and bottomwalls of the cans are fastened thereto.

The invention embraces also other improvements in machines of thischaracter, as will hereinafter more fully appear. I

An organized machine in which my improvements are shown as embodiedembraces generally a suitable die-press which carries avertically-reciprocating punch, a plurality of dies with which saidpunch cooperates, a carrier for said dies bywhieh the dies are carriedto and from the punch, and means for ejecting or removing the can-bodiesfrom the machine after the flanges are-formed thereon. The carrierherein illustrated consists of a rotary dial or disk which is mounted onthe base of the die-press to rotate thereon, but may be made of otherform.

The machine is herein shown as adapted to form both inturned andoutturned flanges on a can-body, though it may be employed forseparately forming either kind of flange.

The invention consists in the matters hereinafter set forth and moreparticularly pointed out in the appended claims.

In the drawings, Figure 1 is aside elevation of the machine embodyingmyimprovements. Fig. 2 is a top plan View thereof with parts shown insection. Fig. 3 is a sectional detail taken through one of the dies andthe punch before the punch has been depressed upon the die. Fig. a is asimilar view of saidparts adjusted to form an outturned flange. Fig.

5 is a similar view of the parts shown in Fig. 3 after the punch hasbeen depressed and an inturned flange formed on the can -body. Fig. (iis a bottom plan view of the punch.

Fig. 10 is a sectional view of one of .the dies and illustrates a partof the ejector device iuposition to eject a can-body from said die.

Fig. 11 is a sectional detail on linellQll of Fig. 2. Fig. 12is asectional detail on line 12 12 of Fig. 7. Fig. 13 is a perspective viewon a small scale of the can-body having an inturned flange formedthereon. Fig. 14 is a sectional detail of the bed-plate, taken on line14: 14: of Fig. 2.

First describing the general construction of the machine in which myimprovements are embodied and referringv more especially to Figs. 1, 2,and 3,'A designates abase of adiepress provided on its upper surfacewith a bed-plate A, and A designates a column rising from said base atthe rear end thereof and provided over the bed-plate with guides or waysA in which travel a vertieally-recipro eating head A which carries atits lower end a punch, (indicated as a whole by B.) Said headisconnected with and actuated from a crank-shaft A by .means of aconnecting-rod A, which shaft is mounted in the upper end of a column Ain the manner shown in Fig. 1.

O designates a horizontal rotary carrier or dial which is mounted torotate upon a concentrically-loeated pin or stud a, formed on or seatedin the bed-plate A.

D D designate as a whole a plurality of dies, which are mountedon therotary carrier or dial 0, said dies being annularly disposed and equallyspaced about said carrier.

E designates a horizontally-movable slidebloek which travels in guidesor ways a, affixed to or formed on the base of the machine at one sideof the carrier. Said slide carries a dog E, located above the ways, theouter end of which dog engages peripheralnotches c in the carrier andthe rear end of' which is pivoted to swing in a horizontal plane on apivot-stud e, rising from the slide. The tail e of said dog is engagedby a spring E herein shown as made spiral and which tends to throw theforward end of the dog toward the carrier and tends to maintain the sameengaged with the notches c. The carrier rotates in a direction thereverse to that of the movement of the hands of a clock, and the rearsides of the peripheral notches c with respect to their direction ofmovement are inclined to permit dogs to bedisengaged therefrom when theslide which carries said dog is moved rearwardly. When said slide ismoved rearwardly, the dog passes from the notch previously engaged by ituntil the end of said dog enters the notch 0 next in rear. At this timethe direction of motion of said slide is reversed and engagement of thedog with the carrier causes the carrier to be rotated one step inadvance or a distance equal to the distance between the centers of saiddies. The actuating devices are soconstructed that when' the carrier isarrested one of the dies is beneath the punch in position to cooperatetherewith in the next depression of the punch.

to a stud a, rising from the slide E. The upper end of'said bell-cranklever is pivoted to one end of a connecting-rod A", the other end ofwhich is pivoted to a stud a mounted on a disk A, which latter isafflxed to the crankshaft A 'Said stud a is adjustably affixed to saiddisk to permit it to move toward and from the center'thereof, the studin this instance being movably fixed in a groovea extending across saiddisk through the center thereof. The adjustment of the connectingrod Aon the disk A is provided for the purpose of enabling the actuatingdevice to be accurately adjusted with respect to the carrier, so as tocenter the dies. thereon with respect to the punch.

Next describing the construction of the punch 13 and referring moreparticularly to Figs. 3, 4, 5, and 6, said punch is made as follows:'The punch consists mainly of a horizontal plate B, provided with a shankb, by which it is connected with a head A and wings or segments Bprovided with lugs b, by which they are pivoted in overlapping relationto extensions or lugsv on the plate, wherebythey are free to swingdownwardly andoutwardly, as shown in Fig. 3, when the punch is elevated.Said wings or segments form when folded together, as shown in Fig. (3, acontinuous rim adapted to fit outside the can-body on the dies, ashereinafter described,

and when closed togetherare desirably of exterior circular con formationto fill the depressions in the carrier in which the dies are located.The spreading of the wings enablesthe punch to freely slide over thedies,

notwithstanding slight irregularities in the centering of the dies andalso to correct any irregularity in the position of the can-bodies. Saiddies and punch are made of the same shape as the can-bodies on which theflanges are to be formed. In the present instance the punch is made toflange can-bodies of oblong, generally rectangular, shape, such assardine-cans; but it will be understood that if cans of other shapesuch,forinstance, as cylindric--the dies and punch will be correspondinglychanged in shape. Each of said wings includes part of the end and partof the side of the punch shell or rim, and the lugs b, by which they arehinged to the punchplate B, are formed on the wings adjacent to thecorners thereof, so that when the wings swing downwardly and outwardlythe punch opens equally in'all directions. Said wings when they assume ahorizontal position are brought together to form acontinnous shell; butwhen the punch is raised the inner or free ends of the wings drop downby gravity, as shown in Fig. 3, thereby throwing outwardly theenteringedges of the wings and expanding or enlarging the hollow of thepunch for the purpose above stated. The wings are provided interiorlybetween the vertical walls of the shell and short inwardlyextendingflanges at the upper edges thereof with rounded or inclineddeflecting-surfaces b the purpose of which will hereinafter appear.

The dies D consist each principally of a center block and a base or dieplate D The center block of the die is made horizontally expansible andconsists principally of three parts-namely, a stationary member D andtwo movable members D D which are pivoted at their ends remote from thestationary member upon studs d rising from the dieplate D The other endof said movable members or those adjacent to the stationary member swingoutwardly and oppositely in a horizontal plane. The adjacent surfaces ofsaid movable and stationary members are inclined to permit such relativemovement, as clearly shown in Fig. 7. The exterior contour of the centerblock formed by said members D D is made of the same shape as the hollowpart of the punch, and the can-bodyF (shown in Figs. 3, 4:, 5, and 8)fits over said center block and within the punch. The body is placed onsaid center block when the movable members D thereof] are in theirinnermost position, as shown in Fig. 7, and said members are thereafterexpanded outwardly to grip the body tightly thereon before the hollowpunch descends upon said block and inoloses the body; The expansion ofthe center block is effected in this instance by means of anexpansion-pin B which projects downwardly from the plate of the hollowpunch inside'the shell thereof and is adapted to engage an opening 61 inthe center block, formed one-half in each of the adjacent sides of thecause said wings to swing inwardly to close the same together around thecenter block."

As will be seen by an inspection of Figs. 3 and 4, said wings when thepunch descends pass readily outside the body F, which has been placedover the center block, and when the wings strike the deflecting-ring thewings are caused to move inwardly and closely em-' brace a can-body.Just before this occurs the expanding-pin B enters the opening d in thecenter block and causes said block to expand outwardly against the body,whereby said body is held firmly in place between the punch and centerblock.

My improvements are designed to form either an inwardly or outwardlydirected flange on the can-body.

I will first describe the operation of forming an inturned flange andrefer more particularly to Figs. 3 and 5 in the description of suchoperation. The center block is made of slightly less thickness than thevertical width of the can-body, so that when the body is placed thereon,as shown in Fig.8, the upper margin thereof projects slightly above saidblock. With this construction when the punch descends upon the die andthe body placed on the center block thereof the defleeting-surfaces b insaid punch strikes the margin of said body which projects above thecenter block and serves to turn said margin inwardly, and the continueddescent of the punch folds said margin down upon the upper surface ofsaid block at substantially right angles to the body to form an inturnedflange f, as shown in Fig. 5.

I will next describe the operation of forming an outturned flange on thebody and refer more particularly in said description to Fig. 4. Beforeproceeding to such description, however, it may be observed that in someinstances it is desirable to form a flange on both margins of the body,an inturned flange on one margin and an outturned flange on the other.The body illustrated in Fig. 4c is shown as having been previouslyformed a with an inturned flange by the operation illustrated in Figs. 3and 5 and just described and as being ready to have formed thereon onits lower margin an outturned flange.

WVhen the body has been previously formed with an inturned flange, asshown in Fig. 4,

the die is provided with a center block thinner than the blockpreviously used equal to the width of stock used in making the inturnedflange. Said center block is vertically movable with respect to the baseD and when an outturned flange is to be formed on the lower margin ofthe body said block is raised a slight'dis'tance above its base and heldyieldingly in such position till thepunch descends thereon, the punchcarrying said block downwardly until arrested by contact with thedie-base. The center block is raised from the die-base andheld in thisposition in the present'instance by the following devices:

G G designate vertically-movable pins fitting vertical openings in thecarrier or dial and the die-base and made of slightly-greater lengththan the combined thickness of said base and the carrier. Said pinsengage'at their upper ends the lower surface of the center block, sothat when they rise the center block is raised off said base.

d d designate guide-pins projectingupwardly from the die-base andfitting loosely in guide-openings in the members of said center block topermit said block to rise and at the same time hold the same laterallyin place. Said pins are headed at their upper ends to limit the upwardmovement of the center block. The guide-pins d fit ininclined slots inthe movable members D of the center block to permit the requiredhorizontal movement of said members. The pivot-lugs d of said movableparts also fit loosely in their pivot-apertures to permit such verticalmovement of the center block with respect to the die-base. The die-basein this instance is provided just outside the center block with adeflecting-surface 01 which when the can-body is placed over the centerblock is engaged by the lower margin of said body. die-base may be usedfor both operations by reversing the base. The pins G G when the centerblock rests upon the die-base project at their lower ends below the dialor carrier and in the operation illustrated in Figs. 3 and 5 are adaptedto rest in suitable openings on the'upper surface of the bed-plate ofthepress. Said openings are inclined, as indicated in Fig. 5 thereof, toenable the pins G G to pass out of the same upon movement of thecarrier. The pin G, located directly under the expanding-pin B is madelarger than the pin G to take the increased strain coming upon this partof the block. In the operation illustrated in Fig. 4 said pins areadapted to be engaged by plungers H, rising upwardly from a horizontalplate H, located within a suitable opening a in the base of the press.Said plate is mounted to slide vertically on a too The same studHfl-located in said opening a having screw-threaded engagement at itsupper end with the bed-plate of the press. Said. plate H in theoperation illustrated in Fig. a is adapted to be held upwardly againstthe bedplate to project the plungers H upwardly and through thepins G Gto raise the center block oil the die-base. This is effected through themedium of a spiral expansion s'pring H surrounding said stud andinterposed between said plate H and a nut h at When the center the lowerend of the stud.

block is raised off the die-basein the manner described and shown inFig. 4E and the can- I body is placedthereon, with its lower marginengaging the deflecting-surface d on the die- 5 base, the descent of thepunch upon and around said body and block tends to depress said centerblock in contact with the die-base against the action of the spring Hand the lower margin of said body byreason of its enro gagement with thedeflecting-surface on the die-base is caused to be flanged outwardly,the entering edges of said hollow punch in the final descent of thepunch flattening said flanges between the same and the horizontal partof the die-base to properly form said flange.

In the operation illustrated in Fig. 3that is, when an inturned flangeis to be formed the nut h is turned downwardly, so as to render thespring H inert and permit the plate H and plungers H to drop downwardlyand also the pins G G, whereby thecenter block is permitted to restdirectly upon the die-base.

The movable members D of'the center block are placed under the influenceof springs which tend to hold said members in their innermost positionswhenv not engaged by the expanding-pin B This construction is shown inFig. 7 and consists of pins d passing upwardly through curved slots insaid members 0 occupying the outer ends of said slots when the membersare in their innermost positions, and spiral expansion-springs d areinterposed between said pins and the inner ends of said slots. It willbe observed also that the carrier in the construction shown projectsbeyond the bed-plate, and it will be necessary, therefore, in practiceto incline the part of said bed-plate A which the pins G G first strikewhen passing onto the bed-plate, as

40 shown in Figs. 2 and 14, to enable the pins to for holding said wingstogether and horizontal until this level is passed. This is accomplishedin thepresent instance by means of spring-pressed pins 0 Figs. 7 and9,which pass upwardly through apertures in the dial plate or carrier 0into the openings in which the dies are mounted and adapted to engage attheir upper ends the free ends of the wings of the punch. The pins areprojected into said openings by spiral expansion-springs O located insuitable'sockets in the carrier beflanges have been formed thereon.

means consists of an ejecting device by WlllClL tween the heads of saidpins and headless screws 0 located in said sockets.

Means are provided for automatically removing the can-bodies from thedies aftersthe aid the bodies are raised from the center block press.

and a knock-off device by which said bodies after being raised areremoved from the dies to a receptacle placed in suitable position toreceive the same. The ejecting device is shown in Figs. 1, 7, and 10 andis made as follows I designates an ejector-ring which is located in eachdepression or opening surrounding each die, said rings being made ofsuch size as tofit snugly in said openings. Each ring is'provided with aplurality of inwardlyshown in Fig. 12. Said ejector-ring is providedwith a plurality of depending pins 1 which pass loosely through openingsin the carrier and are adapted to be engaged by suitable mechanism belowthe same for raising the pins and ejector-ring- The means for so raisingthe pins and ring consists, as herein shown, of a pluralityof plungers JJ, which rise upwardly from a horizontal plate or cross-bar J, attachedto the upper end of a post J engaged at its lower end by the outer orfree end of a vertically-oscil'latory lever J Said lever is pivotedbetween its ends to a depending'lug a attached to or formed on the baseof said A spring J is interposed between a collar on the lower end ofpost and an arm a projecting from the base of the bed-plate,

which tends to hold said post J and the pins J in their lowermostpositions. The free end of said lever is swung upwardly to raise theejectorring through the mechanism described by means of a dog 8 pivotedto a rearwardly-projecting arm on the slide E in such manner as to swingfreely rearwardly, but incapable of swinging forwardly from a verticalposition. When said slideE is moved rearwardly, said dog engages theupturned or inclined endj of the lever J and depresses the rear end ofsaid lever, which causes the forward end thereof to rise and theejectorring to be thrown upwardly. Upon the return movement of saidslide the dog 6 swings rearwardly and permits the same to ride freelyover the upturned portion 3' of the arm J The upward or ejectingposition of the ejector-ring I and associated parts is indicated indotted lines in Fig. 10. Upon the disengagement of said dog 6 from saidlever J the spring J" returns said lever and the ejector mechanism totheir normal positions.

When the can-body has been raised by the ejector mechanism in the mannerdescribed, said body is acted upon by a knock-oft de vice to remove thesame from the machine, said knock-off device being constructed asfollows: K designates an arm or lever which is pivoted between its endsupon astud a ,rising upwardly from the bed-plate of the press. Theforward end of said lever is located just inside of one of the diesthedie upon which the ejector device is in position to act at the time thecarrier is brought to a stop. Said lever is adapted to be actuated justas the body is raised in such manner that the forward end thereof isswung outwardly away from the center of the carrier, and thereby comesin contact with the body and acts to throw the body off of the die andcarrierinto a receptacle placed to receive the same. The means for thusactuating the arm or lever consists of a pin a rising upwardly from theslide E and adapted to engage an inclined part 76 of the lever K, whichis disposed at an angle to the forward end of said lever.

It will be seen, therefore, that when the slide E moves rearwardly thepin 6 contacts with said angularly-disposed arm of the lever K andcauses the forward end of said lever to move radially outwardly. Therear end 7r of said lever beyond the parts 7:; thereof is made of suchlength as to prevent the pin 6 becoming entirely disengaged from thelever, and in the forward movement of said slide the pin rides back onthe lever, and when it has passed the angularly-disposed part 70'thereof said lever assumes its normal position, with its forward endinside the adjacent die under the influence of a spring K.

In order to insure that the can-body is placed properly upon the centerblock before the dies pass under the punch and without the necessity ofthe operator using great accuracy in so placing the can-bodies, I haveprovided a gage-plate which is constructed to perform this work afterthe can-body has been fed to the die and before it has passed under thepunch. Said gage is designated by the letter L in Fig. 1 and is providedwith a rigid arm L, by which it is attached to the cross-head A so as tomove with the punch.

- Said gage consists of a flat horizontal plate and is adapted to bebrought into contact with the upper margin of the can-body and push thesame down over the cent-er block and is provided also with pins l,adapted to engage the fingers I of the ejector-rings I to depress saidrings into their proper positions. It will be understood that thegrooves in the ends of the center blocks formed to receive the ends ofthe ejector-fingers I do not continue to the upper surface of theblocks, so

that said ejector fingers and ringsare prevented from rising above saidblocks.

It is obvious that many changes may be made in the details ofconstruction without departing from the spirit of my invention, and I donot wish to be restricted to such details except hereinafter made thesubject of.
